  • ASR M08-B资料

    ASR M08-B设置软件 V3.2  arduino 2560+ASRM08-B测试程序  arduino UNO+ASRM08-B测试程序语音控制台灯电路图及C51源码(不带校验码) 继电器模块设置。   ASR M08-B是一款语音识别模块。首先对模块添加一些关键字,对着该模块说出关键字,串口会返回三位的数,如果是返回特定的三位数字,还会引起ASR M08-B的相关引脚电平的变化。【测试】①打开“ASR M08-B设置软件 V3.2.exe”。②选择“串口号”、“打开串口”、点选“十六进制显示”。③将USB转串口模块连接到语音识别模块上。接线方法如下:语音模块TXD --> USB模块RXD语音模块RXD --> USB模块TXD语音模块GND --> USB模块GND语音模块3V3 --> USB模块3V3(此端为3.3V电源供电端。)④将模块的开关拨到“A”端,最好再按一次上面的大按钮(按一次即可,为了确保模块工作在正确的模式)。⑤对着模块说“开灯”、“关灯”模块会返回“0B”、“0A”,表示正常(注意:0B对应返回值010,0B对应返回值010,返回是16进制显示的嘛,设置的时候是10进制设置的)。

  • 基于嵌入式ARM的远程视频监控系统研究

    随着科技的进步,视频监控系统正在向嵌入式、数字化、网络化方向发展。嵌入式视频监控系统充分利用大规模集成电路和网络的科技成果,实现了体积小巧、性能稳定、通讯便利的监控产品。 本文以S3C2410为核心硬件平台开发了基于嵌入式的远程视频监控系统,并对关键技术进行了论述和研究。首先给出了系统总体软硬件设计方案,针对本系统硬件对vivi进行了修改和移植,对编译和移植Linux内核以及制作YAFFS文件系统也做了深入的研究,重点讨论了在嵌入式Linux操作系统下开发USB接口摄像头驱动程序和利用linux提供的Video4Linux API函数实现视频数据采集,其次采用背景差法实现了对视频图像中运动目标的检测,然后通过MJPEG压缩算法实现了视频数据压缩,接着介绍了在Linux下基于TCP/IP协议的socket编程,实现了视频数据的网络发送。最后着重论述了嵌入式Web服务器的设计,编写了视频监控主界面程序,并实现了基于B/S模式的视频监控系统结构。 本系统采用模块化设计方法,使得设计更加简洁、高效,具有良好的扩展性和易用性,有利于系统升级。另外采用嵌入式的方法,系统成本较低,易于推广使用。

    Atheros无线芯片AR-6000系列wince 6驱动源代码(这东西我也没用过别问我,我是搜别的wince资源搜到的) AR6K SDIO support. Requires firmware 1.1 on SD13 cards. readme: Atheros Communications AR6001 WLAN Driver for SDIO installation Read Me March 26,2007 (based on k14 fw1.1) Windows CE Embedded CE 6.0 driver installation. 1. Unzip the installation file onto your system (called installation directory below) 2. Create an OS design or open an existing OS design in Platform Builder 6.0. a. The OS must support the SD bus driver and have an SD Host Controller driver (add these from Catalog Items). b. Run image size should be set to allow greater than 32MB. 3. a. From the Project menu select Add Existing Subproject... b. select AR6K_DRV.pbxml c. select open This should create a subproject within your OS Design project for the AR6K_DRV driver. 4. Build the solution. 转自Tony嵌入式,原文地址:http://www.cevx.com/bbs/dispbbs.asp?boardID=4&ID=11762&page=1
